.INVERTED INCANDESCENT GAS-LAMP.

Application filed January 12, 1916.

To all whom it may concern Be it known that I, ROBERT E. Bovine, a citizen of the United States, resldlng at i Gloucester City, in the county of Camden and-State of New Jersey, have invented a new and useful Improvement in Inverted Incandescent Gas-Lamps, of which the following is a full,clear, and'exact description,

reference being, had to the accompanying drawings, forming part of this-specification,

Figure 1 is a side elevation partly in section of the device; 'Flg. 2 1s a side elevation "of the lower portion of the fixture; Fig. 3

' i is a sectional plan view on the line IV-IV is an elevation of the candle casing; Fig.

- of Fig. 3; and'Fig. 5 is a detail plan view of the centering ring.

'My invention relates to .inverted incandescent gas lamps, and particularly to an imitation candle lamp in which the burner vtype'which may be easily assemblednand apmechanism is inclosed within the imitation candle casing.

The object of the invention is to provide a simple, cheap and efiicient lamp of this plied, and is of neat and attractive appearance. The structure is particularly adapted for the C. vE-Z incandescent gas lamp, such as shown in the Lyon Patent No. 1,158,2%9, although it may be used with other inverted cluster burners. It is designedfor attachment to the ordinary gas fixture.

In the drawings,- Qrepresents a coupling thewlower portion 3 of which is internally threaded to fit on the ordinary fixture nipple. Y The upper portion 4 is externally threaded to screw into the lower portion of thevalve casing 5, which contains the by pass-valve 6, having the projecting operz-tting handle 7. Into the upper end of this valvecasing is. screwed anextenslon 8 of the valve casing, which is shown as having 1 two diameters, the. upper part being re- ..duced and externally screw threaded so as to receive the base 8 of the .Bunsen mixer tube 9. This base contains the needle valve I controlling the jet opening, which needle "valve-is-controlledby the side screw 10, or ii;other;,adj.usting means. The pilot tube 11- extends from the lower valve casing up- Specification of Letters Patent.

wardly to the pilot tip 12, this tube extendmg' along thevalve extension to the Bunsen tu e.

To cover the valve casing and form a base for the imitation candle casing, I provide a two-part casing or husk. The'lower portion 13 of this shell is slotted into its upper portion at 1% to receive the stem of the valve and has an intermediate-hole I5fat one'sid-e to give access. to the adjusting screw for the pilot tube. The lower endportion .of this lower part fits against the lower part of'the valve casing and is clamped by the upper shoulder on the coupling for fastening; the lamp to the fixture tip. The

' upper portion 16 of this two-part huskor shell has a projecting lower beadportion which'fits within the upper end of the lower portion of thisshell and the holethrough this upper portion is of such a size as to enable it to be slid down over the Bunsen tube and pilot light tube into itsv nesting position. Thereafter the imitation candle casing 17 is slid down over the top ofthe Bunsen tube, its lowerend fitting 011 the recessed inner shoulder ofthe upper l portion of the husk or shellb This candle casing may be madeof any suitable material, preferably fiber, externally painted white, or

any desirable color, and having two piercings in its side. The upper circularnpiercing '18 is to give access to'the adjusting means for the needle valve, while the lower horizontal slotted portion 19 is to admituair to the Bunsen tube. This air opening is preferably provided with a shutter device 20, having a handle by, which it maybe 0perated. This. lower slot and air shutter, if

the latter is used, are concealed within the upper separable portion of the husk, or

.shell.

, To center the imitation candle casing and also to clamp the parts in place on the Bunabove thercentering ring, has side; slot to receive the Bunsen tube and is clamped to the Bunsen tube by any as the clamp screws 23.

Where the C. E-Z small limp mantle suitable means, such burner is to be used on this lamp, the burner tube .24 for supporting the mantles is slipped on the top of the Bunsen tube, this fixture portion being the same as. that now 1n general use by the l/Velsbach Company under the patent of Lyon above mentioned, and others.

The parts above the candle casing may be concealed by a shade or globe which may be supported on the top of the C. E-Z burner.

If glassware is to used, I preferably provide the globe holder whose central portion is adapted to engage and snap over the centering ring previously described. This globe holder may have any suitable means for holding a globe 26 which will project up around the burnersand mantles, and conceal the same.

The advantages of my invention will be 'obvious to those skilledin the art. It provides an eflective imitation candle fixture WlllClllS of attractive appearance, the burner mechanism being hidden and the lamp being capable of easy and quick attachment The air enters the candle casing within the I gas jet outlet.

upper part of this husk or shell and thence travels up ,to the Bunsen inlets in the upper portion of the casing where the projecting screw gives capacity for adjustment of the The pilot tube is hidden within the candle, casing and the burner parts are concealed within the glassware or shade device.

Many changes may be made in the form and arrangement of the parts without cleparting from my invention.
